> That is... also a way to look at it.

Yeh, the mathematically correct way. There are only about 4-5 generations of humans on the planet at any given point in time. Only the youngest of those can create the next generation. If each generation is getting smaller than the previous because the fertility rate's low, why would you expect population to stabilize?

> Migration is a thing, so unless total fertility is sub-replacement,

Outsourcing your fertility to countries with rapidly declining fertility probably isn't a long term (or short term) fix for the problem.

> "functionally extinct" is a tad bit premature.

In less than 25 years, it will be global. Unless you believe that in a handful of African countries that it will stay above 5 forever, even though it was twice that less than 80 years ago.

> the fact of group size temporarily inducing stress-related infertility until a population is below

So, you believe that all the little girls who exist today, who grow up as only children, who have no aunts or cousins, who see their school teachers childless, all their role models childless... they'll grow up themselves and say "Wow, I want 9 children of my own!"?

I think you're confusing the models here. The moose don't have low fertility, it's as high as ever, but the wolves eat so many offspring, or the food sources so sparse they starve.

In the stress-induced models like Calhoun's mice, population never recovers. The mice become extinct. Even though there's plenty of food, plenty of water, plenty of entertainment. Even after the population crashes, and there's no overcrowding, even then their fertility rates are so low that they just go extinct.

I have no doubt that unless you're in your 60s, you'll one day come to understand that I was correct. This is coming, and nothing other than underwhelming horror at the thought of me being correct explains why you choose to argue about it. HN is filled with people who understand how to predict trends with lines on a chart, and you know or could quickly verify which way fertility numbers are trending. Which direction it is that they can only trend, at this point. "Functionally extinct" is indeed the perfectly correct term for this. It's what you call a species that still has living extant specimens, but for which there is no realistic way for the species to survive in the long term. That's humans.
The difference is that thermodynamic analysis of solar panels, even before building them or improving them, tells us that it is a winning bet. We can't say the same for carbon capture. It's a thermodynamically losing bet.

The humongous amount of entropy we will have to generate to offset any significant part of current emissions via carbon capture (let alone already emitted CO2) basically tells us that carbon capture can only be used in exceptional circumstances where there are no feasible methods of reducing emissions. If there are, then the winning method is to not emit in the first place.
Also, there are very large and as-yet-untapped lithium deposits in the US, not to mention a burgeoning recycled lithium supply chain.
Yes I think I agree. You're describing data startups more than "AI" startups (although of course to investors and prospects they are AI STARTUPS).

If you build a good system to collect hard-to-gather, rich proprietary data then improvements in AI will help you squeeze more and more insights out of it.

Aren't batteries quite limited in their ability to provide synthetic inertia? Sure, they can respond on a second or tenth-of-second scale, but they don't provide the kind of instantaneous inertia you get from spinning rust. Inverters aren't exactly designed to just eat power surges, they'll instantly disconnect instead.

That's why the UK grid has been building some "high-inertia synchronous compensators", and a 2019 outage showed that it's urgently needed.
For sure! Don’t see any reason why it couldn’t be made for anything else. The only baseline is TailwindCSS currently.

Hi HN,
I took some time off my regular job to create a real-time AI (GPT-4 Turbo) powered meeting copilot. It started off as a bit of fun learning a bit more about speech to text with AI prompting but turned into something I think is super useful!

Considering how important style is in most genres, I think the swipe interface could be a good way to quickly find better potential matches, assuming there's a pre-filter based on your selected genres.

If I was looking to start a band today, I'd definitely give this kind of thing a try.
I'd prefer shorter times on road trip charging, too. But I still ended up buying an EV because I only need road trip fast charging a few times a year, and now I don't have to carve out 20 minutes every couple weeks to go find a gas station and fill up. The overall time savings for me is significant.
People absolutely can break multiple bricks or boards, without fakery[0]. Or are you referring to specific videos?

[0] "Fakery" including scoring the wood. But multiple breaks usually takes some setup, such as putting small spacers between the pieces of whatever you're breaking. If you consider that fakery, then ... I guess?
People think these tools are more capable than they are because marketers encourage that misrepresentation. This leads to a huge glut of scam companies that are nothing more than wrappers on OpenAI's GPT tech, or chaining together tools from cloud providers.

I had the chance to talk with one of the healthcare startups, they're trying to make a product that competes with Dragon DAX Copilot (which is incredible) by cobbling together some of the tools from Azure, Google Cloud Platform, and AWS. I didn't believe their pitches, and their prices were insane, because they got some seed funding and are building an MVP still, while also trying to get some revenue. They shared with me a document that was confidential because anyone with technical know how could see they had nothing unique, they were only shuttling data between a couple cloud providers to utilize different pre-built technologies. When confronted with this they got rather defensive and moderately offensive, and even tried to end-run around IT by going to providers and filling their heads with nonsense.

Right now AI can do 10% of what people promise it can, and it's so new audiences don't have the tools to know who is real and who is a fly by night operator. It's like the beginning of the app store, AI is full of incredibly low effort apps right now and most are garbage. People are rushing in like it's a gold rush, they want some easy money before bigger, more competent products come out.

I'd say this is the biggest issue, too many ethically challenged people are spinning up cheap minimum-viable-product apps and slick marketing materials to take some cash off the table before collapsing. The industry is full of snake oil.

Raw HTML for sure, but CSS will be a little bit more tricky, unless you don’t mind generated styles.

Why every time obesity is brought up it's always because the environment is bad, food is bad, lifestyle is unavoidable instead of just being a personal responsibility?
For the purposes of key generation, however, wouldn't you want the full n bits of entropy? Otherwise the search space for a brute force factorization (haha right) is 2^(n-1) instead of 2^n, or half as many possibilities. The domain of the product is still [0..2^(2n)] so the resulting key is the desired 2^(2n) bits.

I guess another way to pose my question would be: is there an issue with sampling the entire 2^n space that makes us only take the highest 2^(n-1) subset of integers instead when selecting factors for a key?

In a free market, if there is a market need for more efficient achievement of redress for wronged parties, the market will produce it.

But of course relying on governments to achieve redress for wronged parties works just great. Not.
The vast majority of mammalian biology research is based on mice. So many ‘in mice’ studies cross this forum, but this is the first time I’ve seen the ethical aspect raised.

Some people (including myself) only need cars for long-distance trips where air or train travel is not feasible, and for most people, even if their car is mainly a grocery-getter, psychologically, they want to know they can drive across the country with it.

Because then people would drill down and either find their perfect partner quickly, or figure out there's nobody compatible with them on the app quickly; and either way, delete the app.

Dating app monetization creates a principal-agent problem: both subscriptions (for paid apps) and advertising/data-brokering (for free apps) are revenue streams that depend on people engaging with the app as much as possible — which people who actually manage to find solid romantic relationships won't do.

The only good dating app monetization model, would be a one-time-fee model. This would induce the correct incentives: as long as people are on the app, they continue to be a cost burden on the service with no further revenue — so, like people hogging a table at a restaurant, the service would be motivated to satisfy them and get them out the door!

But AFAIK, nobody has ever done this yet. (I think it's just because such a site would make so much less money than the traditional "milk your user base eternally" type of dating site. And people who build dating sites are usually in it for the money.)

note that your last optimization of increasing the number by 2 if it fails rather than generating a new random number actually breaks the security slightly. Primes aren't evenly distributed, so doing this biases you towards primes that are directly after large prime gaps.

It seems to me you're precisely proving their point. The drill section starts with:

> there’s a whole range of cases where people don’t have to know exactly how something is intended to be used in order to successfully finish a task

You're demonstrating being able to get a screw in with it without understanding what it does: it doesn't change the power supply at all, but I can see how you might accidentally use it somewhat correctly while applying this assumption. Isn't that basically what OP meant to demonstrate there?

You should quarantine them until you’ve analyzed them.

Like you stated, an async process using a function would suffice. Previously used ClamAV for this in a private cloud solution, I’ve also used the built in anti-virus support on Azure Blob Storage if you don’t mind multi-cloud, plus an Azure Function has the ability to support blob triggers, which is a nice feature.

The file types scan is relatively simple. You just need a list of known “magic string” header values to do a comparison, and for that you only need a max of 40 bytes of the beginning of the file to do the check (from memory). Depending on your stack, there are usually some libraries already available to perform the matching.

And it goes without saying, but never trust the client, and always generate your own filenames.

Your points are well taken. I am an average consumer, one who is retired, I can't afford to gamble on a product that costs so much to maintain. So, I do research to see what is happening in the market. I can't think of a test case better then the one Hertz provides me for free. They ran the numbers and determined EVs just aren't worth the gamble. (most rental cars are usually driven in town, which is mostly what I do.) They're getting out and I'm not getting in.

Scoring is absolutely fakery, and sometimes the boards are cut 90% of the way through on the hidden side (evidenced by clean breaks). So are spacers because "breaking X boards" means stacking the boards directly on top of each other, not using the leverage of displacement of breaking each one one at a time.
I knew a trader in Texas in the 00’s. Worked with to oil traders. Total hearsay but heard stories from this person of traders in TX calling friends they grew up with who worked in Cushing Ok (large pipeline exchange or w/e the technical term is) to adjust the flows a bit over lunch and then change it back.

So, I believe it
While I am sure there are faked videos out there somewhere I have personally performed multiple non-fake multi-board breaks as have many other people. Generally there is one "trick" though: pencils or small wooden dowels are used to space the boards apart which makes the stack of boards weaker than if they were stacked without spacing. I'd argue this is an allowable aspect of showmanship in that five separated boards is cooler looking than two or three stacked without spacing!
I think this is changing. Previously you had to train something massive off a huge data set. But now it's moving towards having a pipeline of pre-trained models that are trained on massive data sets and then smaller models that you train in house to tweak results from that pipeline. Any start-up should be able to get its hands on enough data to train a LoRA for example. There are good enough open source components to build a moat out of a good pipeline with one or two components in the pipeline trained in-house and the rest pretrained.
Good analysis, until you got here:

> While this is a baseless comment, let's look at it anyway:

It's not baseless. This is a golden boy startup, blessed with save the Earth kudos and highly subsidized. The DOE spun this outfit up in 2020 with $19M. Michigan and Whitmer have fast tracked the one, modest, token plant, delivered the tax breaks and signed the contracts for a sodium battery power facility in the state. VC money chased after all this as you would expect.

Those are all temporary or one-time goodies. This is heavy industry and at some point all the love goes away: the subsidies go away, the exemptions go away. Then the foreign competitors steal your tech and undercut you.

At that point you have a choice: fail, or build out where labor is cheap, workers are disposable and regulators are just low-cost party agents, and use your position as US company to readily import your foreign made products.

Notice how none this has anything to do with what raw materials are involved or battery chemistry. It's not about those things. It never has been. The fact that the US has large reserves of sodium is not a factor: filling a ship with sodium and sending it to some foreign plant being only the most obvious thing to do.
You certainly can, provided you have a truck, and a DOT certified fuel trailer, and a transfer pump.

That system also allows you to participate in oil futures as an end user, not to mention it lets you keep your generator up and running for a very long time.

Downside is, modern e10 gasoline tends to adsorb water from the air over time, so fuel isn't stable long term. Most guys doing this are running diesel cars/gensets for that reason.

The model is, go to a truck depot with a 300 gallon trailer, fill up trailer and truck, park the trailer at home. Then fuel the truck off the trailer until it needs to be filled again, repeat. Do understand that, you can get a larger tank, but anything over 1000 gallons requires a placard/permit to haul around. That's in a single tank, so, in theory, a legal length 5th wheel trailer could have multiple tanks under that and be compliant. If you want the tanks attached to a vehicle itself, the maximum size is 150 gallons, hence why semi trucks have multiple fuel tanks that are smaller than that.

Really the only difficulty is finding a place nearby that is willing to sell that much fuel to an individual.
The funniest part is that the way Toyota hybrid powertrains work, if either the ICE or electric motor doesn't work, you cannot go anywhere. It's LESS systemically reliable than either a purely ICE or purely electric powertrain, and yet STILL Toyota hybrids are some of the most reliable cars you can buy.

Their engineering is just that insanely conservative. They just make giant, absurdly understressed engines. You can pull a 2.5L 4cyl engine out of a Camry, designed to make 180 horsepower, replace only a few components, and make 400hp with the reliability you would normally expect from an engine built for endurance racing. They are super popular in drift racing leagues.

> If they could hire fewer people who crank awesome shit out they would.

I don’t know this is true. My personal experience across a dozen jobs is that the only metric that really matters is “how low can you go?” Cost is the thing to minimize and quality is the absolute first thing to be considered optional and to be cut to fulfill the cost objective. Closely followed by “how fast can you go?” Not a pleasant way to work.
This is a conversation close to my heart, and I'm glad to see it discussed.

However:

> 3. Yes, it adjusts the torque of the head

Is not, in my opinion, a good answer.

I would suggest "Yes, it limits the torque of the drill.", or even "Yes, it limits the amount of torque the drill applies to the bit." I would also remove #1 (or consider both #1 and #3 to be correct). Many users would think that is what is happening, and, quite frankly, it doesn't matter whether or not they know what's going on, under the hood.

The user's mental model is really important; much more important (IMNSHO), than the mental model of the developer. Discovering and reinforcing user mental models is a really important part of UX design (In my experience). I have found that it is better that I adapt to the user's mental model, than it is to force them to adopt mine.
